To all yw/zom 'it may concern.' l

Be it known that l, JOSEPH M. CRUCET, a citizen ot the United States, and a resident of the city, county, and State of New York, have invented certain new and useful lmprovements in a Lamp Shade, of which the following is a full, clear, and exact description. l' l Alniong the principal objects which the present invention has in'view are: to form a solid and durable frame for shades of the character mentioned; to adapt the frame to be readily upholstered; to ventilatethe frame; to avoid burning the same; vand to simplify and cheapen the construction.

Description.

Heretofore, lamp shades have been constructed of a variety of materials both for the frame and for the translucent covering panels or ornamentation. The frames, however. have usually consisted of wire or of ratan or similar materials. Wood has been used very slightly if at all, due to the difliculty and expense incident to forming the necessary joints.

As seen in the drawings the frame when constructed in accordance with the present invention has a rim 11. The rim may be circular or polylateral. The rim as seen best in Fig. lof the drawings has adjacent the lower edge thereof a rabbeted member 12 within which rests the head 13 of a fringe 141. The rim is provided above the member 12 witha recess 15 disposed lengthwise in which may be mounted adhesively or otherwise an ornamental fillet to enrich the appearance of the frame.

The rim is operatively connected'with the ground ring16 by a number .of radially disposed ribs 17, The ribs' 17 as seen best in Fig. 5 of the drawings'are rabbeted on both sideedges to form at Tlshape in; cross section, the web 18 whereof supports the eX- posed flanges 19 which overhang the translucent panels 20. A y Y The ground 'ring 16 is circular in form having` a molded surface 21 and aA pendent flange' 22. 'The ring v16 has an open cent-er dividedP horizontally-in service by a metal disk 23. The disk 23 is held permanently in the ring 1'6 by 'a wooden thimble 24 which as seen best in Fig. 3 of the4 drawings has aV vertical extension andhorizontal flange 25. The flange 25 of the thinrble "211 is usually as wide as the lowe'redge of the flange 22 of theV ring 16 being? used' in' practice to cover the lower'edge or'f'aceo'f the said liange 22, and to support the endsof the ribs 17. To receive the ends of' the ribs 17 the flange 22 of the ring 16 are cut away'to form recesses to receive the ends of the ribs 17 and of the web 18 thereof, the top of said ribs forming the flanges 19 being cut back to avoid` themolded surface 21 of the ring 16.

When the ends of the ribs 17 are thus disposed in the recesses formed in the flange 22 they are housed therein by placing the thimble 24 in position which is thenk permanently secured adhesively or otherwise to the flange 22. When the thimble 211 is thus disposed, the recesses in the ring 22 are covered at the inner side of the flange 22 and at the underside thereof. It is obvious that the ribs 17 are thus held positively in position, and that the structure formed thereby is clean. workmanlike and strong.

yWhen the ribs 17 have been mounted, it will be found that the frame provides a series of flared open-ings in which is mounted the panels 20. The panels 20 are usually constructed of mica or parchment or similar material. In some instances frailer material such as transparent Silks are employed. The panels are held in service by fillets 26. `The fillets 26 are secured to the ribs 17 as shown best in Fig. 5 of the drawings. l

The disk 23 has a central perforation 27.

The perforation 27 is provided to receive a.

central rod usually screw-threaded7 of the lamp" pedestal. When the rod is secured firmly in these perforations it is obvious that the frame is held rigidly in service position. A series of perforations 28 surrounding the central; perforation 27 is usuf ally employed for ventilating the lamp shade permitting the heatedair to rise upward therefrom.

`When thepwoodfworik abovedescribed has been united inthe manner explained it may lne-coated orcovered with anysuitable form of service ornamentation such as molded i plaster ;-or mastic compositionsA common to the manufactureof picture frames and, articles of a simiilar` character. When so ornamented and provided with. the fringe 14, a handsome and substantialstructure is obtained."

1 `A lamp" shade comprising a` continuous outerrim; a `center mngsard ring` having a series of bottom openingV recesses; a plurala series `of bottom opening recesses; a plu-` rality of radial ribs structurally connected with said rim, the inner ends of said ribs beingdisposed inthe recesses in said ring; ahousing member permanently attached to saidring to cover the inner and lower surfaces thereof; and a supporting member eX- tending across the opening in said ring to receive the support for said shade.

3. A lamp shade comprising a continuous outer rim; a centerring, said ring having a series of bottom opening recesses; a plurality of radial ribs structurally connected with. said rim, the inner ends of said ribs being disposed in the recesses in said ring; a housing member permanently attached to said ring to cover the inner and lower surfaces thereof; and a metallic disk shaped to conform with the central opening of said ring, and for being held in service relation thereto by saidhousingmember.

4. A lamp shade comprising a rim constnucted `of wood having a rabbeted recess adjacent the lower exposed edge thereof;

an open centered ring concentric to said rim; a plurality of radially disposed ribs structurally connected with said rim and said ring said ribs being rabbeted at the sides to form receptacles for translucent panels: a supportingmember for the inner ends ofsaid ribs, said member being pen manently and structurally connected' with` said ring; and a metal disk mountedin said ring extending across the passageV therein and provided with cnpeningsV for Ventilating saidl lamp shade.
